Intelligent reverse connection protection ensures that power reverse connection will not damage the IC. The IC control circuit and the LED point light source share a power supply. The control circuit and the RGB chip are integrated in a 3528 packaged component to form a complete external control pixel. Built-in signal shaping circuit; any pixel point receives the signal after waveform shaping and then outputs, ensuring that line waveform distortion does not accumulate. Built-in power-on reset and power-down reset circuits. Each pixel's three primary colors can achieve 256 levels of brightness, enabling full true color display of 16,777,216 colors, with a scanning frequency of no less than 400Hz. The serial cascade interface can receive and decode data through a single signal line. When the transmission distance between any two points is less than 5 meters, no additional circuit is required. At a refresh rate of 30 frames per second, the number of cascaded points is not less than 1024. Data transmission speed can reach 800Kbps. Light color is highly consistent and cost-effective.
